| 摘 要： | 提出了在电磁搅拌制备半固态A356铝合金浆料时插拔Cu棒的一个新工艺.由于在半固态铸锭轴向区域引入低温,可进一步提高电磁搅拌效果,铸锭各部位均由细小α-Al晶粒组成.该工艺还可适当提高低过热度浇注的温度而有利于实际生产.

| Abstract: | Because of the solidifying characteristic of alloy and the difference in thermal conductivity of mould,the microstructures of different zones of semi-solid slurry are different,which is hard to satisfy the requirement of rheoforming.A new process preparing semi-solid slurry is proposed,in which a locally rapid cooling near the center zone of mould can be realized by inserting a copper rod into the slurry and then pulling out repeatedly,except application of a weakly electromagnetic stirring. Semi-solid A356... |
